Answer: C) O Explanation: Given series is A F Z U G L T _ Starts with A A + 5 letters = F go to end of alphabet= Z Z - 5 letters = U from F go one more to G + 5 letters = L from U go one back to U, T - 5 letters = O   Second Method :: Change the letters to their corresponding number. A=1 B=2 C=3 ... Z=26 A F Z U G L T _ 1 6 26 21 7 12 20 ? Look at the pattern: the 1st and 3rd numbers = 27, 1+26 the 2nd and 4th numbers = 27, 6+21 the 5th and 7th numbers = 27, so the 6 and 8th would also equal 27. 27 - 12 = 15, so the letter is O.

Answer: B) 60 degrees Explanation: Given the angles of a quadrilateral are in the ratio of 2:4:7:5Let the angles of a quadrilateral are 2x, 4x, 7x, 5xBut we know that sum of the angles = 360 degrees.=> 2x + 4x + 7x + 5x = 360=> x = 20Therfore, the smallest angle of the quadrilateral = 2x = 2x20 = 40 degrees.One of the angle of the triangle = 2 x 40 = 80 degreesThe other angle is 180 - (40 + 80) = 60 degrees. Hence the second largest angle of the triangle is 60 degrees.
